Support brackets are commonly welded to embedded plates, but are not required in this analysis.
Eff. Depth: Distance from center of the tension force to the extreme compression ‘face’ (the bottom edge of the vertical element(s) of the bracket).
Eff. Width: Width of the bracket that is compressing the concrete. May be the sum of the width of the vertical elements of the bracket.
Note: Bracket Dimension can be 0, only if both Mux=0 and Muy=0.
The analysis assumes that a compression block forms at the base of the bracket. Using a Whitney stress block, you can write an equilibrium equation:
